I've heard somewhere that its not good to have your scratch disk set on your boot drive, is this true? Final Cut performance is most important, but i would also like to archive my DVD collection to be a media server to my Apple TV etc. so storage for all that has to come from somewhere. NOTE.. i would like to reserve my 4th bay for windows only drive and a software raid will be used for these. what would you think is a better set-up, 3x internal drives (all of the same model, probably WD 640's) set in raid 0 (both serve as boot drive and scratch disk) occupying bays 1, 2, and 3. In this set-up, everything (DVD's, music, photos, final cut media) would be stored on this array. OR 1x large boot drive (probably 1TB) in bay 1 and 2x internal drives (probably WD 640's) in bays 2 and 3 set in raid 0. In this set-up, DVD's, music, and photos would be stored on the boot drive, while the raid array would only be used as a scratch disk and store final cut media files again performance is most important and don't worry, i have a external back-up solution for this. Thanks in Advance.
